Question
Chapter 19, Problem 17WIO
Summary Introduction
To analyze:
The way a slight change in flower structure may lead to the development of new plant species and how the coevolution results in the huge diversity of the
Introduction:
Vascular plants that produce seeds are known as angiosperms. Their reproductive organs are flowers with ovules protected by an ovary. Angiosperms may be found in practically every environment, from woods and grasslands to seashores and deserts.

Some angiosperm species have exclusive relationships with just one species of pollinator. How would this relationship benefit the plant? What are the risks to the plant?
If there is a steep decline in the population of the major pollinators in an area, which of the following angiosperms would be most directly affected: aspen trees, pear trees, or dandelion plants? Why?
There are the two main characteristics specific to members of angiosperm and attributed as the reason for their success and diversity. What are they and explain how each contributes to the success of this group of plants

- Ferns are a type of terrestrial plant that does not produce seeds, unlike gymnosperms and flowering plants. This significant evolutionary divergence contributed to the dominance of gymnosperms and flowering plants. How might the ability to produce seeds have advantaged these groups? It allowed these plants to photosynthesize more efficiently. It allowed these plants to attract more pollinators. It allowed these plants to better disperse, colonize new habitats, and survive drier conditions. It allowed these plants to grow taller and compete for sunlight.arrow_forwardMost angiosperms incorporate the assistance of animals in their reproductive cycle. This is a major advancement that gave them an advantage over other plant lineages and helped them become the dominant type of plant on Earth today.
